Adjustable LCA's worth it or not?

**davidz28** · 10-22-2011, 07:33 AM

I am looking to purchase some lower control arms for my 2001 z28, I'm wondering if the adjustable ones are worth buying over the solid nonadjustable? I do alot of autocross but im not sure even if I get the adjustable if ill know enough about adjusting them to help any? I am lowered and have SFC's lca relocations, panhard bar, and some other suspension upgrades. I guess my main question is will I ever even use the adjustable feature?

Being that you're lowered and have brackets, I'm betting you'll benefit from adjustable.

I went backwards, I got adjustable because I plan to lower.

After installing mine, I had to move the axle back, so I was glad to have it, but on the other hand, if I had solids, I may not have ever needed to move it back in the first place

Typically you only need adjustable LCA's if you ever plan on running a different tire (slick) or if you plan on upgrading your rear end. Example: the Moser 9" along with a new drive shaft needs about 1/4" of extra room. With adjustable LCA's you can lengthen them and have the rear end sit back further for that clearance if needed.

When you lower the car, the rear end shifts towards the driver's side. An adjustable pan hard bar will correct that.

I am lowered and have non-adjustable LCA's and my wheel sits perfectly centered in the wheel well from eye-balling it.

However, it's nice to always have the feature of adjustment "just in case".

Hey guys. Agree as above. We recommend adjustable in cases you may add other pieces, may do some racing, etc. It's always nice to have that option. For daily drivers where you want an increase in performance but usually don't get under the car except to change the oil twice a year it's often good to go with non-adjustable. We have customers who enjoy tinkering twice a week, for them, adjustable is the way to go.

my only issue with mine is that i have this constant clunking sound if im on a rough surface...road reflectors are horrible...cant quite figure it out...seems to only be on the passenger side

check the nut to see if something came loose. if not, check the bushing.

ive done everything several times, i think its just road noise im gonna have to deal with until i get rid of the decarbons

at first my axle was bumping on the exhaust pipe over there, but i moved the axle back, this sound is very similar, but not quite as intense...as long as i'm on smooth roads its fine...ill prob move the axle back a little more just to be sure, and maybe take an impact hammer to flatten that area of my exhaust pipe a little....

i have full umi adjustable LCAs and PHR. ITS WORTH IT!!! after install the rear of my car was stiffer and i could feel the lauchs planting harder. well worth the investment especially if your lowered.

oh yeah thats def true...after my install of just the LCAs i went out and beat on mine...totally different beast

Thanks guys. It is amazing what LCA's and brackets do for a car. Even after all this time we look at factory pieces in amazement and think, wow, how did these survive...
